Abstract: A method can include transmitting, by a base station to a wireless device, a radio resource control (RRC) message to transition the wireless device from an RRC connected state to an RRC inactive state. The RRC message can indicate a time period in which the wireless device is reachable by paging. The RRC message can be configured to trigger the wireless device to transition from the RRC connected state to the RRC inactive state while remaining in a connection management (CM) connected state. The RRC message can also trigger the wireless device to monitor, in the RRC inactive state, to receive a paging message during the time period after the transitioning. The RRC message can further trigger the wireless device to, in response to an expiration of the time period, stop the monitoring to receive the paging message.
